Question

When would an object stop emitting radiation? when it reaches -273 Kelvin when it reaches 0 Kelvin when it reaches 0 Celsius it would never stop emitting radiation

Answer 1

Objects stop emitting radiation only at 0 K, but objects may not reach 0 K, ever. Thus, no object would ever stop emitting radiation.

Answer 2

Answer: Second option is correct.

Explanation:

When the object is at absolutely 0 kelvin, the object would stop emitting radiation.

Temperature affects the radiation as temperature estimates the average speed of molecules and atoms that is used to made up of any substance and temperature leads to hotness if it increases.

And we know that heat transfers from hot to cold surface object.

If the object is cold then radiation would stop to get emitted.

Hence, Second option is correct.
